Aflatoxin-contaminated corn in Kentucky can now be mixed with other corn provided it will result in a blend safe for feeding to specific animals. The University of Kentucky (UK) College of Agriculture’s Division of Regulatory Services and Kentucky Department of Agriculture okayed the practice that, under normal circumstances, is prohibited.

High levels of aflatoxin, a mycotoxin produced primarily by the fungus or mold, Aspergillus flavus,have contaminated Kentucky cornfields hard-hit by drought. Several states have requested waivers from the FDA.

The waiver establishes procedures for mixing. Before mixing, each producer must sign an agreement with UK’s Division of Regulatory Services. Corn with levels above 500 parts per billion cannot be blended.

Blended corn cannot be sold for human consumption. It is allowed for use in feeds for mature poultry, breeding swine and finishing swine weighing more than 100 lbs, breeding beef cattle and finishing beef cattle. It cannot be used in feed for dairy animals or young livestock, and it must carry a precautionary statement that lists acceptable uses.

Before the blended corn is shipped, it must be tested and certified that the aflatoxin content does not exceed the levels approved for its intended use. For specific details and to request a waiver, visit the UK Division of Regulatory Services Web site or call 859-257-2785.

Monitoring aflatoxin levels in Kentucky corn will continue, and that information will be used to determine the ongoing need and enforcement of the waiver.
